Letters Patent'No. 91,536, dated June 22, 1869.

To allwho m it may concern:

Be it'kno'wn thatl, Josnru 0. HENDERSON, of the city of Troy, in the LGQllllbYiOf vReusselaer, and State ot New York, have inventeda new and improved Stove for burning hard and soft coal; and I further declare that the vfollowing is a full'and exact description of my said invention, reference being had to the accom-. panying drawings, and to the letters of reference marked thereon, in which-'-,

Figure 1 is a side viewof my improved stove.- :Figure 2 isa back View of the same.

- Figure 3 is a viewof the same, with that portion forming the combustion-chamber IBIHOVBQ aHd show-- ing thecylindcr or magazine; I,

Figure 4 is asectionof said stove perpendicular to in which air is supplied to the surface of the fire.

Figure 6 represents the lower portion of the supplycylinder, forming the fire-pot; and the aperture through which the products of combnstionescape. I

Figures? and 8 are sections .of myfsaid' improve stove, showing different modifications of my invention.

The arrows in each of the drawings show the direction. of the draught.

The nature of my invention consists in the construction of a self-feeding or. magazine-stove, with a continuous supply-cylinder, and-with a large aperture in saidv cylinder,ator near the surface of, the ignited coal in the lower part thereof, for the escape of the products of combustion, as hereinafter. specified.

It also consists in theeinployment of a free gas-combustion chamber, surrounding the lower portion of said supply-cylinder, and having an exit-flue at the lower part thereof, substantiallyas. hereinafter specified. 4

It also consists in making an upper chamber in said stove, surrounding the upper part of said supply-cylinder, which is entirely disconnected with the said gas: combustion chamber, as hereinafter specified.

'It also consists in carrying the heated air and'products of combustion from said gas-combustion chamher into a flue constructed on the outside of the stove, and through said flue tothe said upper chamber of said stove, substantially as hereinafter described and specified.

It also consists in constructing an oven or, a boilerseat, in such .a manner that it will be heated by the passage of the products of combustionfrom saidlower to said upper chamber, through said outside'fiue, substantially as specified.-

It also consists inthe construction of an air-chamber, in oraround the said supply-cylinder, with apertures opening into the interior of the cylinder, at or near the surface of the fire, for the purpose of supplying the same with atmospheric air, substantially as hereinafter specified.

It also consists in the use of a passage between said upper and lower chambers, closed bya damper, in such a manner that by opening the damper a direct .updraught may be produced, substantially as hereinafter specified. r

To enable others skilled in the'art to which it relates, to make and use my invention, I will describe the construction and operation thereof, whichare as follows:

Figs. land 2 showthe external appearance of my improved stove.

- A is a chamber surrounding the lower portion of the supply-cylinder, and containing an exit-passage at E into the flue I.

. .B is a chamber surrounding the upper portion of the vsupply-cylinder.

The chambers A and B are entirely disconnected, except by an aperture or passage at J, which-is closed by the damperL.

O is a continuous-supply cylinderor magazine, extending from the top of the stove to the ash-pit, and having a grate at the bottom, upon which the fire is kindled.

Ashort distance above the grate, and directly in front ot'thecylinder, I construct the aperture D, with wings reaching to the outer casing of the chamberA, so that the flame and products of combustion, in escaping from the cylinder, will be obliged to flow over the top of the wings in passing to the exit-passage E in the bottom of the chamber A.

I also construct the flue 1, leading from the exitpassage E, and after continuing the same upward for ,Va'convenient distance, I carry it into the upper chamher 3 of my said stove, from which thesmoke and other products of combustion are conveyed by the exit-pipe K. I

- Before carrying the flue I into the chamber B, the said flue is expanded, so as to form the bottom of an oven, F, which eirpanded fiue'o'r oven-bottom is connected with said chamber B.

The top of the said oven F is also constructed in the form of a broad flue, and connected with the exitpipe K, so that the products of combustion, in passing from the chamber A to the chamber B, will pass directly under the bottom of the said oven, and in passing from said chamber B to the exit-pipe K, will pass directly over the top of said oven.

Fig. 7 shows a modification of this idea, by the formation of the upper part of said upright flue I into a boiler-seat, G, by means of which the products of combustion, in their passage from the lower chamber A to the upper chamber B, can be made to heat a tea-kettle or other culinary vessel, as therein shown.

For the purpose of supplying atmospheric air to the surface of the fire, in order to consume the gases evolved during the process of combustion, I construct a portion of the cylinder 0 with double walls, forming an annular air-chamber, as at H.

In the interior of the cylinder, I form small apertures a a, leading into the said air-chamber, and placed just above the front opening, D, in said cylinder.

One mode of supplying said chamber with air is shown in figs. 5 and 10. It consists in making the lower portion of the cylinder, from the top of the airohamber H to the ash-pit, with double walls, forming a chamber which opens into the ash-pit at b, andadmits the air therefrom.

Another plan is shown in figs. 7 and 8. It consists in the employment of an air-flue or passage leading directly from the back of the stove to the annular chamber above described. It is obvious that air may be admitted to this chamber in many difl'erent ways, and I do not confine myself to any particular mode of producing that result.

The operation of my improved stove is as follows:

The fire being kindled on the grate at the bottom of the cylinder 0, and the said cylinder filled with coal, the air rushing through the apertures a a of the airchamber H, mixes with the gases evolved from the coal, and renders the combustion more perfect.

The smoke and other gaseous products of combustion pass through the opening, D, in the front of the cylinder 0, and passing over the wings of the said opening, pass out at the exit-passage E.

That portion of the inflammable gases not consumed at the surface of the fire will pass, thoroughly mixed with air, into the gas-combustion chamber A, when they will have free space to expand, and will be thoroughly and completely consumed.

It is obvious that by causing the whole of the flame and heated products of combustion to pass through a single aperture in the front of the cylinder, I greatly increase both the heat and the illumination in the front of the stove, where it is most required, and that by causing all the said heated products of combustion to pass around from the front of the stove to the back, outside the cylinder, the heating-power of the stove is increased.

The said products of combustion, alter leaving the lower chamber A, are carried through the fine 1 into the upper chamber B, instead of directly to the chimney, as in ordinary stoves.

By this means the upper portion of the stove, as well as the lower, is highly heated, while the said products of combustion, on their passage from the lower to the upper chamber, may be made to heat an oven, or a boiler, or other vessel, as hereinbefore shown.

If a direct draught is desirable at the time of building the fire, or otherwise, the damper L, which is just over the aperture D, may he opened, and there will be dliarect passage from the fire into the upper chamber c ase Fig 8. is designed to represent a stove with a continuous supply-cylinder, but not divided into an upper and lower chamber, and with a flue, M, connected with the bottom of the stove by the exit-passage E, and at the top by the pipe 0, which is opened or closed by the damper P. When said damper is opened, there will be a direct up-draught from the fire through the pipe 0, and when closed, the products of combustion will pass through the combustion-chamber A to the exit-passage E, thus making a revertible flue, in connection with a continuous cylinder.

Having thus described the construction and operation of my said invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The continuous supply-cylinder or magazine 0, in combination with the front aperture or opening, D, constructed as described, substantially as hereinbefore set forth and specified.

2. The continuous supply -cylinder 0, and front opening, D, in combination with the gas-combustion chamber A and exit-passage E, substantially as hereinbefore specified.

3. The combination of the chamber A, exit-passage E, flue I, and upper chamber B, substantially as and. for the purposes hereinbefore specified.

4. The combination of the chamber A, exit-passage E, flue 1, oven 1*, and chamber B, substantially as and for the purposes hereinbefore specified.

5. The combination of the chamber A, exit-passage E, flue I, boiler-seat G, and chamber B, substantially as and for the purposes hereinbefore specified.

6. Constructing an oven, F, or boiler-seat G, in such a manner that the oven or boiler may be heated by the passage of the products of combustion from the lower to the upper portion of the stove, through an exterior flue or fines, I, substantially as hereinbefore specified.

7. The damper L, in combination with the lower chamber-A and the upper chamber B of the stove, substantially as hereinbefore specified.

8. The annular air-chamber H, and apertures 11. a, in combination with the continuous supply-cylinder 0, substantially as and for the purposes hereinbefore specified.

In witness whereof, I have hereunto set my hand, this 2d day of March, 1869.
